eir, Ireland’s leading full-service telecommunications provider, partnered with Expleo to support large-scale transformation while maintaining the reliability customers depend on every day. Over nearly two decades, the relationship has evolved from testing support into a strategic quality partnership spanning programme delivery, quality engineering, intelligent automation, emerging AI enabled initiatives and transformation assurance.
By combining long-term sector knowledge with hands-on delivery expertise, Expleo has helped eir modernise platforms, launch new services, improve speed to market and manage delivery risk across a highly complex national infrastructure environment.

The challenge
As eir’s transformation programmes accelerated, the complexity of delivering change across legacy and modern systems, multiple delivery partners and national-scale operations increased significantly. The organisation needed to modernise platforms, launch new services and evolve its technology landscape — all while maintaining the reliability millions of customers depend on every day. This required a more structured, scalable and consistent approach to quality, alongside a partner who understood both the technical complexity and operational realities of telecoms at scale.
The solution
For more than 20 years, Expleo has partnered with eir to deliver complex business and technology transformation across its core operations. Working as an extension of the eir team, Expleo has evolved from a trusted quality engineering partner into a strategic transformation partner, supporting the successful delivery of major customer, network and enterprise change programmes.
The partnership spans quality engineering, programme delivery, test automation, assurance, intelligent automation and emerging AI capabilities, helping eir modernise critical platforms while reducing delivery risk and accelerating time to value.
A key milestone in this journey was the establishment of a Test Centre of Excellence, introducing standardised governance, scalable delivery models, automation-first practices and reusable assets that improved consistency, efficiency and quality across programmes. This created the foundation for faster, more predictable delivery in a highly complex, multi-vendor environment.
Today, the partnership continues to evolve. Expleo and eir are expanding beyond traditional automation, exploring how AI can enhance operations, improve customer experience and unlock new productivity gains – all through a measured, well-governed approach that aligns innovation with tangible business outcomes.
The outcome
With Expleo as a trusted partner, eir has been able to deliver transformation at pace while maintaining service stability and customer trust. The partnership has enabled faster releases, improved efficiency and stronger delivery confidence, supporting the rollout of new services, modern platforms and national infrastructure initiatives.
One such rollout has been eir’s Next Generation Access (NGA) fibre, which progressed rapidly, reaching over 900,000 premises and continuing to expand towards an ambitious target of 1.9 million premises, reinforcing eir’s position at the forefront of Ireland’s digital infrastructure transformation.
Over time the partnership has created a more resilient, scalable delivery model — positioning eir to continue evolving its technology landscape while reliably keeping Ireland connected.
